Abstract:

Losses play a crucial role when realistic hyperbolic metamaterials are considered. Importantly, losses lead to a broadening of beams propagating through a hyperbolic medium. Here we show that a part of the loss-induced broadening can be attributed to phase accumulation of plane-wave components. This phase accumulation can be canceled out by utilizing hyperbolic media with a negative permeability.
